Abstract

Retrospective study on incidence and progression of retinopathy of prematurity (ROP) was performed in Nakhonpathom Hospital during 1^st  October 2005 to 30^th  June 2007. These were 195 preterm newborns.

They developed ROP 55 cases (25.20%) 27 cases were male and 28 cases were female. Average gestation age was 30.50 weeks and average birth weight was 1,610 grams.

The majority of ROP in these patients were stage I 50 cases (90.90%) stage III 3 cases (5.45%) and stage II 2 cases (3.63%).

When we classified by weight, we found that the patients under 1,000 grams 11 cases developed ROP 6 cases (54.55%) (stage I 27.27% stage III 18.18% stage II 9.09%).

The patients weight 1,001-1,500 grams 66 cases developed ROP 21 cases (31.81%) (Stage I 28.78% stage II and stage III 1.51%).

The patients weighed more than 1,500 grams, 118 cases developed ROP 28 cases (23.72%) all were stage I. We also found that 7 cases of ROP (12.72%) patient had never received oxygen therapy. Most of ROP cases were improved (70.91%).

This study showed that ROP still be the problems of premature babies, that we must watched for all Cases of prematurity that receiving oxygen therapy or not.
